UCSF Banned Sugary Drink Sales, Here Is What Happened Next – Forbes

Pictured here is the logo for the University of California San Francisco (UCSF) medical center ... [+] embedded into the wall of a building in the Mission Bay neighborhood of San Francisco, California, July 11, 2018. (Photo by Smith Collection/Gado/Getty Images)

Imagine that you are at work and thirsty. How easy is it to get a soda or some other sugary drink? Not too easy? Easy? Very easy? Open-your-eyes-and-it-will-be-in front-of-you-easy?

How then might this affect your chances of drinking a sugary drink rather than water and how might this affect your health?

Well, a study just published in JAMA Internal Medicine showed what happened after a big employer banned the sales of sugar-sweetened beverages. Significant changes occurred and, spoiler alert, things didnt go to waist.

The big employer was the University of California, San Francisco (UCSF), which is the second-largest employer in San Francisco and the fourth-largest in the Bay Area with over 24,000 employees, according to UCSF. As part of the UCSF Healthy Beverage Initiative, the mega-medical center has banned the sales of all sugary drinks across all of their venues since November 1, 2015. After that date, no cafeteria, no vending machine, no food truck, no restaurant, and no store on a UCSF campus could sell sodas or any other drink with added sugar. Not in a box, not with a fox, not with a mouse, there was no such drinks sold in the house.

It can be common to find cans of soda being sold at healthcare facilities. Photographer: Carla ... [+] Gottgens/Bloomberg

Now this didnt mean that UCSF employees had to smuggle sodas in brown paper bags into their workplaces and pretend that they were drinking very brownish water. People could still bring whatever non-alcoholic drinks they wanted onto the UCSF campus. They could also step out of their immediate workplaces into the surrounding neighborhoods to buy sugary beverages. Because, after all, how many times have you heard a person complain about not being able to find soda in a major American city?

Therefore, before this sales ban went into effect, a research team at UCSF (Elissa S. Epel, PhD, Alison Hartman, Laurie M. Jacobs, PhD, Cindy Leung, ScD, MPH, Michael A. Cohn, PhD, Leeane Jensen, MPH, Laura Ishkanian, MPH, Janet Wojcicki, PhD, MPH, Ashley E. Mason, PhD, Robert H. Lustig, MD, MSL, Kimber L. Stanhope, PhD,MS, RD, and Laura A. Schmidt, PhD, MSW, MPH) thought that this would be a great opportunity to measure the impact of such a workplace ban. As Epel, first author of the study, a health psychologist, and Professor in the UCSF Department of Psychiatry said, Many hospitals have recently been implementing bans on selling sugar-sweetened beverages, but no one had really evaluated the effects on consumption and health.

The research team recruited 214 UCSF employees for the study that began on July 28, 2015, about three months before the ban had gone into effect. All of the study participants had to be regular sugar-sweetened beverage drinkers, consuming at least 360 mL or 12 fluid ounces a day. Thats the size of an average aluminum beverage can.

At the start of the study, the research team interviewed and examined each participant, taking a bunch of measurements. Physical measurements included each participants height, weight, waist-to-hip ratio, waist circumference, and sagittal diameter. Your sagittal abdominal diameter (SAD) has nothing to do with how much of a Sagittarius you are or how sad you happen to be. It is the distance from the small of your back to your upper abdomen, which gives a sense of how much fat that you may have in your gut.

The team also asked each participant how many sugar-sweetened beverages he or she consumed each day and did blood tests to assess each participants level of insulin sensitivity. Insulin is the hormone normally secreted by your pancreas that helps regulate sugar in your body and sugar move from your bloodstream into the your cells.

Additionally, the researchers randomly chose half of the participants to undergo a motivational intervention. This motivational intervention wasnt quite like the live in a van down the river Chris Farley as Matt Foley speech from Saturday Night Live. Instead, health educators interviewed each selected participant at the beginning of the study. During this fifteen-minute encounter, the educator quantified the amount of sugar that the participant was drinking each day and provided guidance and educational materials on how to reduce sugar intake. The intervention also included five minute follow-up phones calls one week after the initial interview and one month and six months following the beginning of the sales ban. The motivational intervention was similar to the interventions used to make people aware of the dangers of alcohol dependence.

By the way, this Kasier Permanente video, which was not part of the study, shows how much sugar sugary drinks can have:

How sweet then were the results of the study? Well, just ten months after the ban had started, the average daily consumption of sugar-sweetened beverages had gone down from 1050 mL (or 35 fluid ounces) to 540 mL (or 18 fluid ounces) per participant. That was a 510-mL (or 17 fluid ounces or almost a can-and-a-half) drop, which amounted to a 48.6% decrease. The participants who had received the motivational intervention experienced on average a greater drop (762 mL, 25.4 fluid ounces, or two cans worth) than those who had not (246.0 mL or 8.2 fluid ounces).

Thats not all folks. Those who had decreases in daily sugar-sweetened beverage consumption also tended to have decreases in their insulin resistance as measured by lab tests. Insulin resistance is not a political movement but is a situation in which the cells in your body begin ignoring what insulin is trying to do. With insulin resistance, the cells in your muscles, fat, and liver essentially say, bye Felicia, when insulin says take up some sugar from the blood. As a result, your blood sugar levels begin creeping upwards, which can be a major step towards badness such as developing fatty liver disease or diabetes.

Then theres the waist from this study or rather waists. The average waistline measurements decreased by 2.1 cm. Again, just 10 months after the ban had started, noticeable loosening of pants or similar garments occurred in a number of participants. Thats big, or rather less big.

Epel explained that the study period was too short to see significant changes in weight but abdominal fat is sensitive to sugar intake, and we saw significantly reduced waist lines.

Of note, significant decreases in waist sizes occurred among not only those who were in the obesity or overweight categories but also those who fell into the lean category, which was having a body mass index (BMI) less than 25. This was a reminder that even though you may appear lean or skinny, looks can be deceiving. It also matters how much fat you may have sitting in your abdomen.

Ten months is significant because it was long enough for each participant to go through different seasons, as much as seasons exist in San Francisco. The research team wanted to make sure that any observed changes were sustained and not just typical fluctuations that may occur throughout the year. In fact, the observed changes persisted through not just 10 months but 12 months after the ban had begun.

Of course, 12 months is not 15 months, which is not two years, which is not a decade. So, yes, the study did have its limitations and could not tell you if the changes were sustainable over several years. The study also did not track what concurrently happened with other habits such as eating and exercise. Moreover, different workplaces can be quite different, so the question remains: would such a ban have the same effects elsewhere.

Schmidt, the senior author of the study and a Professor of Health Policy at UCSF, did say that their team has started a controlled study in Sutter Health, a large health care system in the Bay Area, that will address some of these limitations and help better nail down the mechanisms involved. So stay tuned.

Nonetheless, this is yet more evidence that your work environment really matters. This is not surprising, since you do spend on average a third of your time at work, maybe more if you are a doctor or a doctor going through training. What you are exposed to at work can really affect what you eat and drink. After all, you are still like a baby in that you tend to put whats close to you into your mouth. The food and beverages that are around you comprise whats called your food and beverage environment.

In fact, changing the beverage environment at work could have a spill-over effect as well, so to speak. People in the study really drank less sugar-sweetened beverages, not just at work, said Epel. They were making equal reductions at home and at work.

Schmidt likened removing soda from workplaces to taking cigarettes out of workplace vending machines. Schmidt is certainly not the first person to find similarities between sugary beverages and tobacco. A number of people have called sugar the new tobacco, including the authors of aCMAJ (Canadian Medical Association Journal) commentary. As I have written previously for Forbes, a report from Vital Strategiesraised concerns that soda companies are using the same marketing strategies that Big Tobacco companies have used.

Sugar does have at least one thing in common with nicotine, it can be addictive. Epel included the following video on food addiction on her UCSF Aging, Metabolism, and Emotion Research website:

Addiction is one reason why sugar exposure at work can affect what you consume at home. As Epel explained, there is deeply ingrained moral ethic of personal responsibility. While theoretically that sounds good, the reality is our brain is vulnerable to addiction. We need to help people be well by creating the right environments. In other words, you are what you are exposed to every day.

Speaking of exposure, marketing is another possible cause of such spill-over effects. If you are exposed to soda is great messages at work, that could potentially influence what you buy elsewhere. No matter how hard you try to separate work life from home life, influences invariably will bubble over in both directions.

While some other healthcare institutions, such as the Cleveland Clinic, the University of Michigan Health System, the Baylor Health Care System, and the Geisinger Clinic, have instituted sugar-sweetened beverage sales bans as well, there are still many healthcare institutions that continue to pour some sugar on their employees. Schmidt pointed out that institutions arrange pouring rights with soda companies. The institutions will then co-brand and market sugar-sweetened beverages. This could be money-makers for institutions, making them more likely to continue to go with the flow.

To re-purpose the words of Alanis Morissette, isnt it ironic for healthcare institutions to help sell sugar-sweetened beverages? After all, many such beverages have no demonstrated nutritional value over water and are in essence liquid sugar, in the words of Epel. As Epel related, you have institutions that are training people to be health professionals and employing people to treat patients but at the same time are serving them sugary beverages.

Its not as if employees at UCSF resisted the ban. Rather, UCSF employees appreciated the care for their health. They were very positive about the ban. In fact, the only people who expressed any concerns were some visitors who didnt understand the culture and wanted to buy sugar-sweetened beverages during their visit, according to Epel.

Of course, healthcare employers arent the only employers that could institute such a ban. Schmidt referred to such bans as low-hanging fruit, as opposed to low-hanging sugar-sweetened fruit drinks. Policy changes such as soda taxes have run into political obstacles. Having employers change their food and beverage environments is a way of getting around such obstacles.

Indeed, employers could have lots of incentive to make such changes. Studies such as one published in a 2014 issue of JAMA Internal Medicine have linked excess sugar consumption to a variety of health problems including obesity, diabetes, cardiovascular disease, cancer, and early death, even for those who fall into the normal weight category. What employers then would want their employees to be as sick as possible? Schmidt pointed out that if you can avert new cases of illness, you can save a lot of money.

The fact that UCSF not only instituted the ban but also provided financial support for the study suggests that employers could help lead the way in curbing sugar-sweetened beverage consumption. Employers may want to pore through this UCSF study before they decide about pouring rights and what to essentially pour on their employees.

CRISPR-Cas9mediated therapeutic editing of Rpe65 ameliorates the disease phenotypes in a mouse model of Leber congenital amaurosis – Science Advances

Abstract

Leber congenital amaurosis (LCA), one of the leading causes of childhood-onset blindness, is caused by autosomal recessive mutations in several genes including RPE65. In this study, we performed CRISPR-Cas9mediated therapeutic correction of a disease-associated nonsense mutation in Rpe65 in rd12 mice, a model of human LCA. Subretinal injection of adeno-associated virus carrying CRISPR-Cas9 and donor DNA resulted in >1% homology-directed repair and ~1.6% deletion of the pathogenic stop codon in Rpe65 in retinal pigment epithelial tissues of rd12 mice. The a- and b-waves of electroretinograms were recovered to levels up to 21.2 4.1% and 39.8 3.2% of their wild-type mice counterparts upon bright stimuli after dark adaptation 7 months after injection. There was no definite evidence of histologic perturbation or tumorigenesis during 7 months of observation. Collectively, we present the first therapeutic correction of an Rpe65 nonsense mutation using CRISPR-Cas9, providing new insight for developing therapeutics for LCA.

Leber congenital amaurosis (LCA) is a hereditary retinal degenerative disease that leads to childhood-onset blindness (1). Among the genes causing LCA, CEP290, GUCY2D, CRB1, and RPE65 are those most frequently mutated. In particular, about 6% of LCA cases are caused by mutations in RPE65 (2). To date, no substantial treatments or cures for LCA have been developed, except for voretigene neparvovec (Luxturna, Spark Therapeutics), which is approved by the U.S. Food and Drug Administration (FDA). This approach is based on RPE65 gene delivery by adeno-associated virus (AAV) to the retina in patients who lack the functional RPE65 protein (35). On the basis of preclinical studies performed in RPE65 null dogs (6, 7) and mice (8, 9), initial clinical trials tested the adverse events and therapeutic outcomes of AAV containing the human RPE65 complementary DNA (cDNA) (35). Although normal vision was not achieved, these trials showed that subretinal injection of AAV had an acceptable local and systemic adverse event profile and improved visual function (10). Nevertheless, because gene therapy cannot totally correct the mutated sequence and has a limitation in the cargo size of the AAV (~4.8 kb) when AAV is used, there are still unmet needs in the gene therapy area for broader clinical application.

CRISPR-Cas9 is a genome editing tool that can lead to the insertion of genes or the deletion of mutations (1115) by homology-directed repair (HDR) or by nonhomologous end joining (NHEJ), respectively. Although the frequency of HDR is generally lower than that of NHEJ, the ability of HDR to correct pathogenic mutations permanently has great potential for curing various genetic disorders (1618). For example, intravenously infused AAV expressing the Cas9 machinery and the donor DNA reversed the disease-causing mutation and rescued the disease phenotypes in two different mouse models of metabolic diseases (1618).

In this context, we hypothesized that CRISPR-Cas9 could represent another therapy for LCA and tested the therapeutic outcomes of CRISPR-Cas9mediated HDR in rd12 mice, a model of human LCA that bears a disease-associated premature stop codon in Rpe65. We used CRISPR-Cas9 technology to correct the nonsense mutation in this model and found that HDR and in-frame NHEJ in response to CRISPR-Cas9mediated DNA cleavage led to the recovery of retinal functions and protection from retinal degeneration. The results from this proof-of-concept study demonstrate the feasibility of our approach and imply that CRISPR-Cas9mediated HDR could be expanded to other ophthalmologic diseases in which HDR might be needed.

To use CRISPR-Cas9 technology to treat LCA, we first screened single guide RNA (sgRNA) sequences targeting Rpe65 exon 3 in the region that corresponds to the C-to-T nonsense mutation locus using mouse embryonic fibroblasts (MEFs) from rd12 mice (fig. S1A). Of nine potential candidates tested, the TS4 sgRNA was selected for further studies because it generated double-strand break (DSB) at the nearest locus from the premature stop codon and resulted in highly efficient insertion or deletion (indel) rates, as determined by targeted deep sequencing when transfected with SpCas9 protein as riboneucleoprotein (RNP) complex (fig. S1B). Next, we examined the correction frequencies by HDR induced by the TS4 sgRNA and Rpe65 donor in rd12 MEFs. Synonymous mutations were introduced into the donor sequence to prevent cleavage of the donor itself or recleavage of the repaired Rpe65 locus after correction (Fig. 1, A and F). Single-stranded oligodeoxynucleotide (ssODN) was used as an Rpe65 donor and induced correction in a range of 3 to 6% (Fig. 1, B, C, and F). When NHEJ was analyzed by deep sequencing, TS4 sgRNAmediated indels were dominated by deletions, and approximately one-fourth of the mutations corresponded to in-frame indels (Fig. 1, D and E). Among the in-frame indels, one-codon deletions accounted for 5.6% of the total reads (Fig. 1F). Because the in-frame indels could result in the removal of the premature Rpe65 stop codon from rd12 mice, we suggest that NHEJ-mediated editing might also contribute to the therapeutic effects of CRISPR-Cas9. These data indicate that we identified an optimized sgRNA sequence for therapeutic, CRISPR-Cas9mediated genome editing to treat LCA.

Error bars indicate SEM. **P < 0.01; ***P < 0.001 by Kruskal-Wallis test with Dunns multiple comparison test.

To evaluate the therapeutic efficacy of CRISPR-Cas9mediated editing of the Rpe65 nonsense mutation in a disease model, we changed one nucleotide in TS4 to design the TS4rd12 sgRNA, which perfectly matches the sequence of the Rpe65 exon 3 mutation locus in rd12 mice. All required editing components were incorporated into two separate AAVs (AAV-SpCas9 and AAV-TS4rd12 sgRNA-Rpe65-donor, hereafter referred to as AAV-TS4rd12-donor), and in vivo delivery was carried out using the dual AAV system (Fig. 2A). We optimized the ratio of AAV components by varying their concentrations to obtain maximized genome editing results. A low dose [a total of 2 1010 vector genomes (vg) per eye] or high dose (a total of 2 1011 vg per eye) of AAVs was administered via subretinal injection into 3-week-old rd12 mice. After 4 weeks of AAV treatment, the targeted region of Rpe65 was analyzed by deep sequencing using cells from the retina and retinal pigment epithelium (RPE). Subretinal injection resulted in indel rates in the retina and RPE that reached ~20% but varied depending on various parameters (Fig. 2, B and C). Low-dose subretinal injection induced low and high indel rates in the retina and RPE, respectively. This result indicates that subretinal AAV administration is more efficient in the RPE versus the retina; this conclusion was further verified by the finding of a higher AAV copy number per diploid cell (Fig. 2D and fig. S2) in the RPE. Because a previous study showed that the use of a high (10:1) ratio of sgRNAs and donor to Cas9 induced a further increase in the frequency of a correction in a mouse model of liver disease (18), an excessive amount of AAV-TS4rd12-donor relative to AAV-SpCas9 (AAV-SpCas9:AAV-TS4rd12-donor ratio of 0.1:1.9) was tested, but it resulted in a lower frequency of indels in both tissues after subretinal administration (Fig. 2, B and C). Collectively, these data suggest that subretinal delivery is an efficient method of inducing in vivo Rpe65 editing and that the Cas9-to-sgRNA ratio is critical for optimized editing.

(H) Nucleotide sequences showing the Rpe65 donor template and changes induced by the TS4 sgRNA in AAV-treated RPE (n = 10).

Violet triangle, position of the DSB induced by the TS4 sgRNA; red text, sequences corresponding to the premature stop codon in rd12 mice; blue text, PAM sequences; green text, synonymous mutations in the donor template; underlined sequences, nucleotides encompassing the premature stop codon and their corresponding amino acid sequences. *P < 0.05; **P < 0.01; ***P < 0.001 by Kruskal-Wallis test with Dunns multiple comparison test (B, C, and E) and Mann-Whitney U test (F).

Subsequently, we analyzed HDR events near the pathogenic C-to-T mutation in Rpe65 in the retina and RPE after AAV treatment in rd12 mice. HDR events were observed in the RPE but not in the retina (Fig. 2E). Although indel frequencies were comparable between low-dose AAV and high-dose AAVtreated RPE when a 1:1 ratio of AAV-SpCas9 to AAV-TS4-donor was used (Fig. 2C), HDR events were more frequent in the high-dose AAVtreated group (high dose, 1.17 0.31%; low dose, 0.59 0.22%) (Fig. 2E), as similarly observed in the CRISPR-mediated correction of the ornithine transcarbamylase gene in hepatocytes (18). Moreover, analysis of the HDR-to-indel ratio revealed that HDR events were approximately three times more frequent in the high dosetreated group (Fig. 2F). Successful HDR (1.01 0.38%) was also induced by the application of a 0.5:1.5 ratio of AAV-SpCas9 to AAV-TS4-donor (Fig. 2E). It should be noted that most HDR events resulted in a precise correction of the T-to-C mutation, so that the resulting protein sequences were identical to that of wild-type Rpe65 (Fig. 2H). We additionally characterized NHEJ-mediated editing in the RPE and found that in-frame deletions occurred at a frequency of 3.83%; 1.61% were one-codon deletions that resulted in the removal of the premature stop codon in rd12 mice (Fig. 2, G and H). The 1-codon-Del-2 type (CGT-deletion) was also predicted as one of the top three end-joining categories (table S1) by inDelphi, the machine learning model that predicts SpCas9-mediated template-free genome editing (19). In addition, substantial in-frame editing was achieved in human RPE65 with the use of various sgRNAs in human embryonic kidney (HEK) 293 cells, suggesting the clinical potential of our approach (fig. S3, A to C).

To investigate the therapeutic effects of HDR-mediated Rpe65 gene correction in rd12 mice, we performed electroretinography after dark adaptation at 6 weeks and 7 months after subretinal AAV injection (Fig. 3A). AAV treatment led to the recovery of Rpe65 expression in RPE cells at 6 weeks after injection (Fig. 3B). Furthermore, AAV treatment resulted in increased Rpe65 gene expression in RPE cells at 7 months after injection (Fig. 3C). In electroretinography, rd12 mice demonstrated severely attenuated dark-adapted light responses compared with age-matched normal C57BL/6 mice (20). In contrast, there were definite responses to bright stimuli (0 dB) by which both rod and cone responses are provoked after dark adaptation in the AAV-treated rd12 mice at 6 weeks after the subretinal injection (Fig. 3, D to F, and fig. S4), whereas there were no responses to dim stimuli (25 dB) (fig. S5). The electrical responses were maintained up to 7 months after the initial injection (Fig. 3, G and H). The estimated a- and b-wave amplitudes were 21.2 4.1% and 39.8 3.2% of those of normal C57BL/6 mice. These functional recoveries were accompanied by anatomical changes in which HDR-mediated Rpe65 gene correction prevented the loss of neuronal cells in the outer nuclear layer of the retina in rd12 mice (Fig. 3, I and J).

To globally characterize potential off-target sites recognized by the TS4rd12 sgRNA, we performed Digenome-seq, a genome-wide unbiased off-target detection method (21), using genomic DNA from rd12 mice. This analysis showed several potential off-target sites (Fig. 4A). We validated the 29 potential off-target sites with the highest Digenome-seq cleavage scores using targeted deep sequencing. Six genomic loci were shown to be actively targeted by the TS4rd12 sgRNA in the retina of rd12 mice (Fig. 4B), and these off-target sites were consistently found to be targeted in the RPE (Fig. 4C). All of the active off-target sites are located in intronic or intergenic regions (table S2). In a subsequent off-target analysis for all 33 homologous sites that differed from the TS4rd12 sgRNA sequence by up to three nucleotides, no meaningful indel mutations were observed at the predicted genomic loci in AAV-treated rd12 mice (fig. S6). In addition, there was no definitive evidence of histologic perturbation or tumorigenesis for 7 months in these mice (Fig. 4D).

In this study, we deployed CRISPR-Cas9mediated HDR as a new treatment for LCA. We showed that dual AAVmediated delivery of CRISPR-Cas9 and an Rpe65 donor sequence can lead to the correction of a disease-causing mutation in Rpe65 and an improvement in retinal function in a mouse model of LCA. In addition to this improvement, our study showed a level of functional recovery that exceeds the measured gene correction level. The results are provocative because in postmitotic cells, HDR events are generally known as rare. However, our observations are supported by recent studies showing CRISPR-Cas9mediated HDR events in postmitotic neurons (22) and muscles (23). Our results are also supported by previous studies in which CRISPR-Cas9 treatment for certain autosomal recessive diseases, such as Duchenne muscular dystrophy (23) and retinitis pigmentosa (24), resulted in functional improvement beyond the level expected from the gene correction frequency. Together, these results suggest that HDR can be activated in these postmitotic cells and that therapeutic outcomes exceeding that expected from the editing level could be achieved in some cases.

Gene therapy works by using viruses as a means of overexpressing wild-type copies of defective, disease-associated genes. For instance, Luxturna, the FDA-approved gene therapy for LCA, uses AAV2 to express functional RPE65 to replace the mutant, LCA-associated RPE65 protein. Different types of viruses, such as lentivirus and retrovirus, can also be used for gene therapy, but AAV is clinically validated (35, 25, 26). Although AAV is very attractive for gene therapy because it does not integrate into the host genome, its limited cargo packaging capability hinders its application in many cases. Therefore, for some ocular diseases such as Stargardt disease or Usher syndrome, which require the delivery of large DNA fragments, our approach using CRISPR-Cas9mediated HDR could be suitable therapeutically. In addition, because the desired wild-type sequence can be introduced at the genomic site where the gene should exist, replacing the mutant sequence by HDR, the HDR-corrected cells can express the introduced genes at the endogenous level. In this study, CRISPR-Cas9 was randomly introduced into the eye by subretinal injection in rd12 mice because mice lack a macula, the center and core of vision in humans. The injection resulted in a frequency of gene correction of nearly 3% by HDR and in-frame NHEJ (Fig. 2, E, F, and H) and led to substantial improvement in electroretinography measurements (Fig. 3, D to H). We expect that these results in mice can be further improved in human patients with LCA because ophthalmologists can selectively perform subretinal injection near the macular area, enabling focused editing around this structure to achieve even more restoration of vision.

The deep sequencing in our study provides a detailed description of the types of indels generated and the extent of off-target mutations produced, which was extensive. Although the active off-target sites that we detected were within intronic or intergenic regions, this level of off-target effects could undermine the therapeutic potential of our approach using CRISPR-Cas9mediated genome editing. As the first study to use CRISPR-Cas9 to treat LCA, we used wild-type SpCas9, the conventional and most commonly used form of Cas9. To reduce the frequency of off-target mutations, high-fidelity versions of Cas9 [HFCas9, eCas9, HypaCas9 (27), SniperCas9 (28), or self-targeting AAV (29)] or inducible-editing (30) could be tried as an alternative. We tested SniperCas9 (28), a high-fidelity version of SpCas9 that was developed by our group in the C2C12 cell line. We found that SniperCas9 was associated with a significant reduction in indel frequencies at the off-target sites recognized by SpCas9 (fig. S7). In addition, SniperCas9 showed comparable activity against the mRosa26 target, indicating that its low level of off-target effects does not come at the expense of on-target activity. These results suggest that various approaches might be tried to reduce off-target mutations in further studies. In addition, the off-target mutations detected in this study might not be found in the clinic because of differences between the human and mouse genomes. Moreover, it is noteworthy that there were no definite morphological changes in the RPE at 7 months after the subretinal injection, suggesting that the off-target mutations do not exert definite harmful effects (Fig. 4D).

In conclusion, we provide a new, CRISPR-Cas9based approach for treating LCA. To our knowledge, no previous reports have shown in vivo HDR-mediated correction in animal models of ophthalmologic diseases. Our permanent therapeutic genome editing approach could be used alone, or together with gene therapy or protein therapy, to treat LCA.

MEFs were maintained in Dulbeccos modified Eagles medium (DMEM) supplemented with glucose (4.5 g/liter), 4 mM glutamine, 1 mM sodium pyruvate, 10% fetal bovine serum, penicillin (100 U/ml), and streptomycin (100 mg/ml). RNPs and 120-mer ssODN were transfected using Neon Transfection following the manufacturers procedures (Life Technologies). Briefly, 2.5 105 cells were mixed with materials for transfection and were subjected to electrical shock using 10-l tips on the Neon system for 30 ms at 1350 V for one pulse. Five days after transfection, the cells were harvested, and genomic DNA was extracted using a DNeasy Blood and Tissue kit (Qiagen). For transfections of HEK293 cells, cells were seeded at 2 105 cell per well into 24-well plates the day before transfection. One microgram of plasmids encoding human optimized SpCas9 and sgRNA was mixed with 2 l of Lipofectamine 2000 (Invitrogen) in 200 l of Opti-MEM, left for 20 min, and then added to cells that had reached 70% confluence in 500 l of DMEM. After overnight incubation, the medium was replaced with 500 l of fresh medium, and genomic DNA was extracted after 5 days of transfection.

Eight-week-old male C57BL/6 mice and mating pairs of rd12 mice (stock no. 005379, the Jackson laboratory) were purchased from Central Laboratory Animal and maintained under a 12-hour dark-light cycle. rd12 mice were mated with each other to produce offspring with a homozygous mutation in the Rpe65 gene. All animal experiments were performed following guidelines from the Association for Research in Vision and Ophthalmology statement for the use of animals in ophthalmic and vision research and approved by Institutional Animal Care and Use Committees of both Seoul National University and Seoul National University Hospital.

To quantify indel frequency, on-target and off-target regions were amplified by polymerase chain reaction (PCR) from genomic DNA extracted from transfected cells, retina, or RPE using the primer sets summarized in table S2. To quantify HDR frequencies, PCRs were first performed from genomic DNA (50 ng) using primers outside of the Rpe65-homology arm, after which products were further amplified to generate amplicons for deep sequencing. The produced amplicons were barcoded during subsequent PCR with Illumina TrueSeq adaptors. The products were purified with a PCR purification kit (Geneall) and were then pooled in equimolar ratio. The final libraries were paired-end sequenced using the Illumina Miseq platform according to the manufacturers protocol. Indel frequencies were quantified using Cas-Analyzer (www.rgenome.net) (31). Quantification of specific patterns such as in-frame or out-of-frame indels, one-codon deletions, and precise HDR were determined by manual counting.

Potential off-target sites were identified using an in silico tool, Cas-OFFinder (32). Mouse genomic sites containing up to 3base pair (bp) mismatches were considered as off-target sites and further confirmed by targeted deep sequencing using the primers shown in table S3.

Genomic DNA was purified from the retina of rd12 mice with a DNeasy Tissue kit (Qiagen) according to the manufacturers instructions. Genomic DNA (8 g) was incubated with purified Cas9 protein (100 nM) and sgRNA (300 nM) in a reaction volume of 400 l for 8 hours at 37C in a buffer [100 mM NaCl, 40 mM tris-HCl, 10 mM MgCl2, and bovine serum albumin (100 g/ml; pH 7.9)]. Digested genomic DNA was purified again with a DNeasy Tissue kit (Qiagen) after RNase A (50 g/ml) was added to remove sgRNA. To check targeted in vitro DNA cleavage, digested genomic DNA was mixed with 2 SYBR Green Master Mix and analyzed by real-time quantitative PCR (qPCR) using forward primer 5-GGACATTCTACATATGAATCCAGG-3 and reverse primer 5-TAACATTCTCAGGTGGCTGTGCAA-3. The fraction of target sites that were cleaved was measured using the comparative CT method (33).

For Digenome-seq, genomic DNA (1 g) was sonicated to produce fragments in the 400- to 500-bp range using the Covaris system (Life Technologies) and blunt ended using End Repair Mix (Thermo Fisher). Fragmented DNA was ligated with adapters to produce libraries, which were then subjected to whole-genome sequencing (WGS) using a HiSeq X Ten Sequencer (Illumina) at Macrogen. WGS was performed at a sequencing depth of 30 to 40, and the DNA cleavage score was calculated using a previously published scoring system (34).

Sequences of the elongation factor 1a short (EFS) promoter and human optimized SpCas9 with a nuclear localization signal, hemagglutinin (HA) tag, and bovine growth hormone poly-A tail were synthesized and subcloned into an AAV2 inverted terminal repeat (ITR)based plasmid using Not I restriction sites. For the other AAV vector, sequences of the U6 promoter, TS4 sgRNA, and Rpe65 donor were also synthesized and subcloned into the AAV2 ITRbased plasmid using the same restriction sites. In the Rpe65 donor sequences, five nucleotides were substituted without causing codon changes to prevent possible TS4 sgRNAmediated cleavage and to precisely distinguish knocked-in sequences from endogenous genomic sequences. Recombinant AAV particles were produced using a helper adenovirus-free packaging system. Briefly, HEK293 cells were cotransfected with pAAV-ITR-EFS-SpCas9 or pAAV-ITR-TS4rd12-sgRNA-Rpe65-donor, AAV9-capsid plasmid, and helper plasmid. After 3 days of transfection, the cells were lysed and the virus particles were purified by iodixanol gradient ultracentrifugation and concentrated to obtain titers greater than 1013 vg/ml.

After deep anesthesia, AAV9-SpCas9 and AAV9-TS4 sgRNA-Rpe65-donor (a total of 2 1010 or 2 1011 vg in 1 l of phosphate-buffered saline) were mixed and injected into the subretinal space of the mouse eye through the vitreous cavity using a customized Nanofil syringe with a 33-gauge blunt needle (World Precision Instrument) under an operating microscope (Leica), as previously described (35).

qPCR to determine the AAV genome copy number was performed using genomic DNA extracted from the retina or RPE. After measuring the genomic DNA concentration using a Quantus fluorometer together with the Quantifluor Dye system (Promega), 50 ng of genomic DNA was subjected to qPCR analysis using an AAVpro titration kit (Takara). Thermocycling conditions were as follows: 95C, 2 min followed by 35 cycles of 95C, 5 s; 60C, 30 s. The number of AAV genome copies was calculated against a standard curve. The number of diploid mouse cells was calculated using a conversion factor of ~1.6 104 diploid cells per 100 g of genomic DNA.

Mice were dark adapted for over 16 hours. After deep anesthesia, pupils were dilated with an eye drop containing phenylephrine hydrochloride (5 mg/ml) and tropicamide (5 mg/ml). Full-field electroretinography was performed using the universal testing and electrophysiologic system 2000 (UTAS E-2000, LKC Technologies). The scotopic responses were recorded with a flash of 0 dB at a gain of 2 k using a notch filter at 60 Hz and were bandpass filtered between 0.1 and 1500 Hz. The amplitudes of the a-wave were measured from the baseline to the lowest negative-going voltage, whereas the peak b-wave amplitudes were estimated from the trough of the a-wave to the highest peak of the positive b-wave.

At 6 weeks after AAV-mediated delivery of SpCas9 and TS4 sgRNA-Rpe65-donor, paraffin blocks were prepared from enucleated eyes. Thin sections were immunostained with anti-HA antibody (1:1,000; cat. no. 3F10, Roche) and anti-Rpe65 antibody (1:1,000; cat. no. sc-73616, Santa Cruz Biotechnologies), followed by treatment with Alexa Fluor 488 or 594 immunoglobulin G (IgG; 1:500; Thermo Fisher). Nuclear staining was performed using 4,6-diamidino-2-phenylindole dihydrochloride (Sigma-Aldrich). The slides then were observed under a fluorescence microscope (Leica).

Total RNA was isolated using TRI Reagent (Molecular Research Center) from RPE cells of rd12 mice at 7 months after AAV-mediated delivery of SpCas9 and TS4 sgRNA-Rpe65-donor. cDNAs were prepared with a High-Capacity RNA-to-cDNA Kit (Thermo Fisher). Real-time PCR was performed with the StepOnePlus Real-Time PCR System (Thermo Fisher) using TaqMan Fast Advanced Master Mix (Thermo Fisher) with Gene Expression Assays (Thermo Fisher) for gene expression analyses. Product IDs of the gene expression assays for genes are as follows: for Rpe65, Mm00504133_m1; for Gapdh, Mm99999915_g1; and for Rn18s, Mm03928990_g1. The relative expression levels of the Rpe65 gene were normalized to those of Gapdh and Rn18s. All procedures were performed in accordance with the Minimum Information for Publication of Quantitative Real-Time PCR Experiments guidelines.

At 7 months after AAV-mediated delivery of SpCas9 and TS4 sgRNA-Rpe65-donor, paraffin blocks were prepared from enucleated eyes. Thin sections were then prepared for hematoxylin and eosin (H&E) staining.

At 7 months after AAV-mediated delivery of SpCas9 and TS4 sgRNA-Rpe65-donor, RPE-choroid-scleral complexes were prepared from enucleated eyes. Then, the complexes were immunostained with antiZO-1 antibody (5 g/ml; cat. no. 61-7300, Thermo Fisher), followed by treatment with Alexa Fluor 594 IgG (1:500; Thermo Fisher). Nuclear staining was performed using 4,6-diamidino-2-phenylindole dihydrochloride (Sigma-Aldrich). The slides then were observed under a fluorescence microscope (Leica).

Here are the important details of the James Younger verdict (FULL RULING) – Lifesite

DALLAS, Texas, October 29, 2019 (LifeSiteNews) LifeSiteNews has obtained a certified copy of the complete ruling in the case of seven-year-old James Younger, whose mother wanted him to undergo a gender transition against his fathers wishes.

Mr. Jeffrey Younger was fighting to prevent his ex-wife Dr. Anne Georgulas from transitioning James into Luna. The custody battle over James and his twin, Jude, garnered national attention after initially being ignored by the mainstream media. LifeSiteNews and The Texan were the only news outlets present for the entire trial.

Judge Kim Cooks ultimately ruled that Dr. Georgulas will not be able to transition the child into a girl without Mr. Youngers consent, and placed a gag order on both parents preventing either of them from talking about the case with media until James and Jude turn 18.

Judge Cooks made it clear she was not happy with the media attention the case received, and Dr. Georgulas lawyers brought up Mr. Youngers speaking to the media. He said he felt the public had a right to know what was going on in the medical field.

Judge Cooks did not uphold the jurys ruling that the current order be modified to provide one of the parents with sole managing conservatorship. She ruled that Mr. Younger and Dr. Georgulas will be joint managing conservators. They will both need to agree on all medical, dental, and psychological/psychiatric care. If a counselor determines it is appropriate, Mr. Younger will be granted 50/50 custody in January or June 2020. Judge Cooks also mandated family counseling for the entire family.

Judge Cooks is the same judge who, in 2017, awarded Dr. Georgulas the exclusive right, after notifying the Father, to consent to psychiatric and psychological treatment of the children and the exclusive right, after notifying the Father, to consent to medical, dental, and surgical treatment involving invasive procedures.

The court also mandated counseling to address specifically outlined issues and issued an injunction against the parents making disparaging remarks regarding the other parent in the presence of the children or in the childrens listening.

Judge Cooks gave the amicus attorney, Mr. Stacy Dunlop, the power to make medical decisions for the boys if Mr. Younger and Dr. Georgulas cannot agree.

If the parents cannot come to an agreement, they will make an appointment with Stacy Dunlop, the Parenting Coordinator, who will resolve the dispute by making a decision on behalf of the parents if they still disagree, the ruling says.

Specifically on medical, psychological, psychiatric, and dental issues, Mr. Dunlop will resolve the dispute by making a decision on behalf of the parents if they still disagree after discussing the disagreement with Stacy Dunlop.

Dr. Georgulas has the exclusive right to the services and earnings of the children, and the exclusive right to receive child support.

The ruling also outlines the courts 68 findings. The court found that there has been no abuse, neglect, or family violence by either parent to the children or from one parent towards the other. The court found, the mother made no request to surgically or chemically transition the childs sex or to chemically castrate the child.

Evidence presented in court indicated Dr. Georgulas had referrals to the GENECIS transgender childrens clinic. Dr. Georgulas also testified that she consulted with the GENECIS clinic about James. Dr. Georgulas expert witnesses testified about the alleged benefits of affirming transgenderism in children, including the use of puberty blockers and cross-sex hormones.

The court found that, the State of Texas has no compelling interest to justify such interference as to entering Orders requiring the Father to affirm Luna and honor her [sic] choices, both inside and outside the home. In other words, Mr. Younger will not be forced to use female pronouns to refer to his son.

One of the court findings highlighted a statement from Dr. Albritton, the custody evaluator, that Dr. Georgulas was over and above affirming. The court also found that the Mother has exceeded the scope of the exclusive rights and duties provided in the prior order.

The ruling also said that the state has not mandated the transition of James directly: No Texas judge or Texas court nor the 255th family court of appeal has ordered the chemical castration, puberty blockers, hormone blockers, or any transgnder reassignment surgery on this child.

Gov. Greg Abbott, Sen. Ted Cruz, and Rep. Dan Crenshaw all of Texas and many conservative leaders weighed in on the case after it went viral.

Sen. Rand Paul, R-KY, tweeted: We dont let kids drink alcohol til 21. People want to move smoking age to 21. But we will allow a 7 year old to have his life and body altered like this? This is child abuse and the state should side with the father who is trying to protect the child.

7 health trends Silicon Valley tech bros are obsessed with, from dopamine fasting to the keto diet – INSIDER

The eating pattern means the clock, not your body, dictates when you eat. TanyaJoy/Getty Images

The trend:

When it comes to Dorsey's fasting style, the CEO chooses to eat one time daily at 6:30 p.m., at which point he'll consume a protein (either fish, chicken, or steak) and some vegetables (an arugula or spinach salad, asparagus, or Brussels sprouts). Then he'll have a dessert of mixed berries or dark chocolate, which he consumes before 9 p.m.

On weekends, Dorsey fasts until Sunday evening. When he breaks his fast, he'll have bone broth and some red wine, though Dorsey didn't specify how often he consumes alcohol.

"It really has increased my appreciation for food and taste because I'm deprived of it for so long during the day," Dorsey told fitness authorBen Greenfield in April during an episode of Greenfield's podcast.

Dorsey's approach isn't the only way to go about intermittent fasting though. There are four popular types, according to the Cleveland Clinic, including a twice-weekly fast and a time-restricted method where a dieter eats only between 11 a.m. and 7 p.m., or between or noon and 8 p.m.

The science behind it:

Some research suggests intermittent fasting can help with weight loss better than restricting overall calories while eating throughout the day.

At the same time, research has found people have trouble sticking to intermittent fasting for the long term compared to other weight-loss plans.

According to the Cleveland Clinic, intermittent fasting isn't entirely proven as a helpful diet, but it does work for some people if they learn how to incorporate it into their lives without feeling deprived.

When it comes to Dorsey's more extreme style of fasting, some professionals see it as disordered eating. And, doing it over a long period of time could be especially detrimental to mental and physical health.

"Humans are mammals that need certain amounts of food and fluid to maintain our physiological [functions] and energy to do things we want to do in the world," Dr. Jennifer Gaudiani, an internal-medicine doctor who specializes in eating disorders, previously told Business Insider.

"When people undercut their need for food with radical under-eating, the body doesn't care about the reasoning. It is just going react to save your life," Gaudiani said.

That reaction will include feelings of mental sharpness because the body is trying to determine when and where from it will get its next meal, according to Gaudiani, which could explain Dorsey's mention of increased mental acuity during the Greenfield interview.

New Study Pinpoints The Ancestral Homeland of All Humans Alive Today – ScienceAlert

A group of researchers say they have pinpointed the ancestral homeland of all humans alive today: modern-day Botswana.

In a new study published in the journal Nature, scientists analysed mitochondrial DNA genetic information that gets passed down the female line from more than 1,200 people across myriad populations in Africa.

By examining which genes were preserved in people's DNA over time, the anthropologists determined that anatomically modern humans emerged in what was once a lush wetland in Botswana, south of the Zambezi River.

Though scientists agree that modern humans (Homo sapiens sapiens) arose in Africa around 200,000 years ago, they have remained uncertain about exactly where on the continent that evolutionary milestone occurred.

The new study offers an answer to that question and also undermines the idea that our ancestors emerged in East Africa, as limited fossil evidence suggests.

The anthropologist Vanessa Hayes, the senior author of the new paper, said in a press conference that the findings suggested "everyone walking around today" could trace their mitochondrial DNA back to this "human homeland."

To trace the geographic origin of our ancestors, Hayes and her colleagues examined mitochondrial DNA (mtDNA) from people living in southern Africa, such as the Khoisan.

mtDNA, which is passed down the maternal line, is often used to trace human ancestry because it isn't mixed with paternal DNA. That means it changes less over time and leaves a clearer link to distant relatives.

When it comes to mtDNA, modern humans all share a group of genes called the L macro-haplogroup.

This L-branch is split into two subgroups: L1-6 and L0. The latter can be found in the peoples of southern Africa, and that's what Hayes' team analysed. Eva Chan, a coauthor of the study, said this was the "by far the largest L0 study to date."

By pulling on that genetic string, the researchers were able to figure out that every person alive today descended from a woman who lived in modern-day Botswana about 200,000 years ago.

The region this ancestor came from, called the Makgadikgadi-Okavango paleo-wetland, was near the modern Okavango Delta and peppered with lakes and greenery.

The team's analysis, which also included reconstructions of what the area's climate was like at the time, revealed that Homo sapiens sapiens lived in this homeland for about 70,000 years.

Then, as the climate changed, our ancestors dispersed in two waves: First, a group spread northeast 130,000 years ago, then others left in a second migration to the southwest 110,000 years ago.

According to Hayes, these migrating groups likely followed herds of animals out of the region.

This timeline runs counter to the one some scientists have created based on fossil evidence, however.

The oldest-ever specimens of anatomically modern humans skulls and other fossils dating back 195,000 years were found in Ethiopia, which led many anthropologists to think of eastern Africa (rather than southern Africa, as the new study suggests) as the birthplace of our modern ancestors.

The new genetic analysis also offers credence to the idea that all modern humans evolved in one place in Africa before migrating to current-day Europe, Asia, and Australia what's known as the "Out of Africa" hypothesis rather than evolving separately in multiple places around the world at the same time.

According to the study authors, the two-wave migration out of Botswana "paved the way for modern humans to later migrate out of Africa, and ultimately across the world."

But the anthropologist Ryan Raaum, who researches African population genetics at Lehman College, thinks the new study has a significant flaw. According to Raaum, the researchers didn't go back far back enough on the genetic timeline.

Though Hayes' research pinpointed where the L0 haplogroup originated, he said, the mitochondrial DNA of most people in the world can be traced back to the L1-6 subgroup of the L-branch, not L0.

So to find a "single origin" for our species, Raaum said, researchers should find a genetic predecessor who lived before the genetic split between L0 and L1-6 occurred.

"Where I get a little lost in the weeds is when they expand out to argue that these data indicate a southern African origin for anatomically modern humans," he told Business Insider. "The data do not."

Raaum added that he didn't like the phrase "ancestral homeland" in general, since modern humans likely had multiple homelands scattered around the African continent.

"I increasingly think that there probably wasn't a single population in which modern humans evolved. If that is the case, there is no 'homeland'," he said.

Another issue with Hayes' team's findings is that an mtDNA analysis examines only maternal DNA.

Two parts of the cell carry DNA: the nucleus, where most of our genetic material resides, and the mitochondria.

Nuclear DNA (nDNA) is inherited from both parents and is what passes along the Y chromosome; mitochondrial DNA, on the other hand, is passed down from only the mother.

nDNA is rare in the fossil record, which is why studies like Hayes' often don't examine it. But that means such research can't examine the entire genome of our ancestral populations.

In 2014, anthropologists pinpointed the oldest known modern-human lineage based on Y chromosome data. This population was at most 160,000 years old and in central western Africa.

So every person alive today likely descended from a man who lived in a different part of the continent than the homeland Hayes and her colleagues suggest.

Hayes noted that a full genome analysis could yield different results: "There could be other origins and other lineages it's a possibility," she said during the press conference.

But whether or not Botswana was the cradle of life for everyone alive today, the new research certainly suggests this part of Africa was an oasis for our ancestors a significant addition to our understanding of human evolution.

"People want know where they came from," Hayes said.

Intersex people on how they want to be treated and accepted – Dazed

It is society that needs fixing, not intersex bodies activists at the Voices4 London demo talk candidly on Intersex Awareness Day

I look forward to a time when parents arent made to feel the need to hide from their child that they are intersex. I look forward to a day when intersex variations are not treated as disorders that need fixing,Rachelle Newman, anintersex activist, said at the London rally onIntersex Awareness Day 2019.

This day was established in 2003 by US intersex activists Emi Koyama and Betsy Driver to commemorate the first public intersex demonstration in 1996. 23 years on, the fight is still ongoing. Intersex is an umbrella term used to describe people born with biological variations in their sex characteristics that dont fit male or female categories. These variations may be present in peoples chromosomes, hormones, genitals and/or internal sex organs, like testes or ovaries. Intersex traits can also be linked to genetic mosaicism, where some cells in the body have XX chromosomes and others XY.

Medicine has traditionally viewed intersex people as needing to be fixed with involuntary medical intervention, also known as Intersex Genital Mutilation (IGM), simply to make their bodies conform to traditional notions of male or female. Many cases of IGM change the appearance or sexual function of a childs genitals and are carried out at a very young age, without consent and often with no transparency regarding the details.

On Saturday October 26, peaceful direct action groupVoices 4 Londonresponded to an international call by theIntersex Justice Projectto organise events in support of The End Intersex Surgery Campaign. Members of the LGBTQIA+ community gathered in Soho Square Gardens in London to offer support and attention to the intersex activists leading the rally. Through the pouring rain, the crowd listened asNewman was joined by Martin Di Maggio and Valentino Vecchietti to call for an end to non-consensual forced surgery, brandishing hand-painted signs with slogans such as Your Body, Your Choice, Your Rights, Delay is Okay, and Intersex Stories Not Surgeries.

This was followed by a short impromptu march, accompanied by shouts of Your Body, Your Choice. The group gathered in front of the sexual health clinic, 56 Dean Street, to celebrate that the intersex flag was flying there for the first time ever in recognition of Intersex Awareness Day. The services are also currently amending their equalities policy to include intersex people.

Here, we spoke with four intersex activists who were present at the rally about what intersex justice looks like.

What one pervasive myth or misunderstanding around the lived experiences of intersex people do you most wish you could address widely?

Rachelle Newman:That we dont exist. There are many activists doing amazing work to improve intersex visibility yet sadly many people still do not know what the word intersex means. I want intersex people to be able to say Im intersex and receive a response not much more than ah okay, cool!.

Whats something about your experience as an intersex person, that you wish people were aware of and understood?

Rachelle Newman:In regards to my personal experience, I wish society as a whole was more aware of and understood the mental health impacts that resulted from my treatment. Being told I was infertile at age 11 was the worst day of my life but I wish people would also understand the impacts of the events that followed. For example, the dread I would feel thinking about my biannual appointments, having to expose my chest to a doctor without knowing why, the daily reminder of taking tablets I did not understand the purpose of and the internal dialogue with myself as I discovered and wondered why my body was different, why I had scars. I wish people would understand the shame imposed on myself and many other intersex individuals from a young age and the negative repercussions of this.

If you could say something to your younger self, what would you say?

Rachelle Newman:You are not alone. One day it will all make sense. You will become strong and when you share the part of yourself that you have been ashamed of for so long you will receive more acceptance than you can imagine. You will learn to love the things you thought you couldnt.

Whats something about your experience as an intersex person, either generally or specifically within the UK, that you wish people were aware of and understood?

Martin Di Maggio: That we have no protection against molestation and sexual abuse, doctors do and have legally gotten away with sexual abuse because they claim they are only doing medical testing. Yet many of us have experienced intrusive examinations that had a doctor done them on an endosex (non-intersex) woman theyd be imprisoned, yet with us, the law doesnt even protect us and doctors go free. Look up the case of Aivar Bracka.

What are your thoughts on the Gender Recognition Actwithin the context of how it might impact intersex people and, especially, children?

MartinDi Maggio:I think that parents being able to put an X marker on a childs birth certificate means nothing for intersex children as long as we dont have protection against IGM. Having X as an intersex child would perhaps just make us more vulnerable to unwanted medical attention.

What is one misunderstanding around the lived experiences of intersex people that you most wish you could address widely?

Izzy MacCallum: One misunderstanding/assumption that Ive noticed a lot of people have is that they think being intersex is necessarily referring to someones genitalia. In reality, there are a wide variety of traits and sex characteristics that can mean someones biology doesnt fit the typical definitions of male or female. Maybe someone has XY chromosomes and testes but a vagina and no uterus. Or someone has an extra chromosome, like XXY, or they could have mosaic genetics. People can have no ovaries or testes or one of each you see what Im getting at.

Whats something about your experience as an intersex person, either generally or specifically within the UK, that you wish people were aware of and understood?

Izzy MacCallum: The argument that these non-consensual surgeries are done to ease the social discomfort of intersex people not only denies the individual bodily autonomy, but it actually perpetuates social discomfort. Intersex people challenge the social norms and understandings of sex and gender as a binary, and by keeping sex and gender within a binary frame it can be used to enforce and maintain social and historical forms of oppression. It is society that needs fixing, not intersex bodies.

If you had to pinpoint it and youre comfortable sharing it, whats the one external or personal thing that has most positively impacted your life so far?

Valentino Vecchietti:I grew up feeling so alone and scared, and filled with shame. But as an adult, finding connection with other intersex people, and finding acceptance and love amongst my friends, has been an amazing and moving journey for me.

How do you think the Gender Recognition Act could betterprotect intersex people and, especially, children?

Valentino Vecchietti:Current medical protocols for intersex kids dont support our human right to bodily integrity and bodily autonomy.We need ethical, patient-centred, healthcare and medical treatment, which must include the option of correcting birth certificates.

If you could say something to your younger self, what would you say?

Valentino Vecchietti:You will find love, you will find friends, you can belong.

If Diabetes Leads to Heart Disease, Should Cardiologists Care For Diabetes? – American Council on Science and Health

I used to think that the brain was the most wonderful organ in my body. Then I realized who was telling me this.

Emo Philips, American Comedian

A research letter in JAMA Cardiology captures the same idea, substituting cardiologist for brain and physician for organ in my body.

Researchers begin by noting that new medications for diabetes also modify the course of heart disease; and that there are increasing numbers of patients with new-onset Type 2 diabetes. They then look at new-onset cases of Type 2 diabetes by state comparing them to the available supply of cardiologists, endocrinologists (physicians caring specifically for diabetes among other hormone-related conditions), and nephrologists (physicians who care for kidney disease). Low and behold, with three times more cardiologists than either endocrinologists or nephrologists, who is well-positioned to participate in diabetes care given their numbers and distribution relative to diabetes cases? Yes, cardiologists.

In addition to their sheer numbers, cardiologists bring other values to the table. Cardiologists see more patients with diabetes than endocrinologists; cardiologists are more frequently consulted in the hospital for issues involving patients with diabetes increasing the teachable moments. And finally, diabetes is becoming less glucocentric and more about global risk reduction. Frankly, who knows more about reducing risk, cardiologists just ask them.

All right, I must confess, I have a conflict of interest here. As a vascular surgeon, I have watched cardiologists claim that they can care for vascular disease, the area I trained in for six years because they are good with wires and balloons and they fix coronary arteries that are very small and important, so the big arteries that I care for are easy. Arteries are arteries after all unless, of course, you are a vascular surgeon that, for some bizarre reason, feels that you should fix a coronary artery with a balloon and stent; then, those arteries are different.

There is an invited commentary from a primary care physician; more specifically, an individual specializes in general internal medicine. He points out that patients often require coordinated, collaborative care, and there is a push to create a medical home, business-speak for having one consistent primary care physician. To extend that medical home metaphor, he points out that other specialists, part of the medical neighborhood, have much to offer, but that the decision to involve the neighbors, like cardiology, nephrology, or endocrinology involved should be made by the patient and their immediate real and medical family.

Collaboration and communication are not easy, even in this day of smartphones and text. It is challenging to coordinate a discussion about a patient using text messaging.; If you think that a physician has a time advantage when calling another physician, then you havent witnessed the dance of competing office staff trying to eliminate any waiting time for their doc - someone has to wait on the line. As a result, coordinating care often means prolonging decisions, increasing patient wait times, and in some instances, anxiety. Who is best qualified to coordinate the neighborhood? I agree with the commentator, the generalist has the best view, seeing more than the heart disease or glucose management.

Why are cardiologists so interested in expanding their lane? Why are they not content, supporting the hard work of primary-care physicians? As we move deeper into team medicine, not everyone can be the quarterback coordinating the play; even that gifted receiver, the one in this instance caring for your heart.

More women are getting breast cancer in their 20s, University of Iowa research shows – The Gazette

IOWA CITY A growing percentage of younger women are getting breast cancer with rates among 20-somethings increasing the fastest, according to new University of Iowa-led research.

Although the overall number of affected women in that age range remains well below other age groups, the rate of 20 to 29-year-olds diagnosed with stage 1 to stage 3 breast cancer increased about 2 percentage points a year during the 15-year study period, according to research published in the September issue of the Journal of the National Cancer Institute Cancer Spectrum.

Breast cancer rates for women in their 30s and 40s also increased from 2000 to 2015, although not as fast, inching up about .3 percentage points a year.

The study looked not only at incidence rates but survival rates and found that, in addition to seeing the largest annual percentage increase, the diagnosed 20-somethings had lower 10-year survival rates than their 30-to-40-year-old peers.

Reasons for the worse outcomes could be multifold and include that younger women often experience diagnosis and care delays in part because breast-cancer screening is less common among that age group.

Physicians might be less suspicious of malignancy in younger patients even when they show up in clinic with a breast lump, according to researchers.

Detecting cancerous growth in younger women also can be more challenging due to their dense breast tissue, according to the studys lead author, UI professor of epidemiology Paul Romitti.

ARTICLE CONTINUES BELOW ADVERTISEMENT

Romitti said the findings could have important clinical and self-care implications encouraging increased education and self-checks at a younger age.

Try to avoid care delays with these women, Romitti said. Be aware that because theyre traditionally not screened to make sure that when patients report a lump in their breast, its checked.

Brooke McKinnon of Coralville said shes glad her physician did, when last December she went in for her annual gynecology appointment. At age 27, the UI graduate and Hawkeye rowing athletic trainer hadnt yet had a mammogram.

But during her appointment, the doctor felt a lump and given that McKinnons mother not even two years before had been diagnosed with breast cancer the physician encouraged her to get a full work-up, while trying to calm her nerves.

Shes like, You know, young women get cysts in their breasts sometimes. She said, Dont get yourself worked up, but lets just get it checked out, McKinnon said.

That guarded reassurance did infiltrate McKinnons thinking as she waited four long weeks between that original appointment and when they could get her in for more imaging and tests.

I kind of convinced myself that Im too young to have breast cancer and this is not cancer and Ill be fine, she recalled.

But ultrasound and biopsy results revealed McKinnon despite her young age did have cancer grade 1B invasive ductal carcinoma. She got the call on a Monday morning and by that afternoon she had an appointment with the breast surgeon.

They mapped out a plan for a lumpectomy and more tests, and just after Christmas she learned her cancer hadnt spread and therefore was considered stage 1.

That was the best news you could get, she said.

ARTICLE CONTINUES BELOW ADVERTISEMENT

McKinnon still endured chemotherapy and continues to undergo hormone therapy in that her cancer cells grew in response to estrogen and progesterone.

Being premenopausal complicates treatment for younger patients, especially those such as McKinnon who havent had children but want to.

Having my own kid is very important to me, so I did IVF (in vitro fertilization) before even starting chemotherapy, she said.

When McKinnon was diagnosed, she was engaged with a wedding date planned for the coming summer. They managed one embryo from the IVF, and she took a drug to protect her ovaries during her cancer treatment in hopes shell be able to conceive without IVF in the future.

After her follow-up radiation, McKinnon today is cancer free and has a good prognosis not to mention a wedding still on the books for June.

Learning that her age group is getting breast cancer at a faster clip than others, she said, was shocking.

Its unsettling, she said.

The UI research in addition to assessing incidence and survival rates by age range looked at different types of breast cancers and variations by race and ethnicity.

Survival rates were lower among those who identified as non-Hispanic blacks and Hispanics, compared with non-Hispanic whites and Asian/Pacific Islanders.

ARTICLE CONTINUES BELOW ADVERTISEMENT

Some of those differences could be tied to variations in access to health care, according to Romitti, who is continuing his research by focusing on Iowa women in hopes of identifying life factors that might contribute to incidence and survival rates.

But based on what this initial research has found, his colleague and co-author at Wake Forest School of Medicine, Alexandra Thomas, stressed physicians should reject assumptions that younger women with lumps in their breasts dont have cancer.

We want physicians to be alerted to the rising cancer incidence among this population, Thomas said.

Medically Necessary Or ‘Cruel’? Inside The Battle Over Surgery On Intersex Babies – wgbh.org

When Kimberly Zieselman was 41, she got hold of her medical records from Massachusetts General Hospital. What she found was shocking.

The words "male pseudo hermaphrodite" were written on her chart.

Zieselman discovered she was born with XY chromosomes. Until that moment, she had no idea she was born intersex, an umbrella term used to describe people born with male and female anatomical characteristics.

As a teenager, Zieselman came to discover, doctors had performed surgery on her reproductive organs in an effort to conform her anatomy to fit one mold a move that had serious psychological ramifications for her later on in life, she said, and that was done without her complete, informed consent.

Like, Zieselman, many intersex adults who underwent procedures as babies have dealt with painful consequences later in life. Now 53, Zieselman has become a part of a growing movement within the intersex community speaking out against surgeries performed on intersex babies. Unless surgery is medically necessary, activists say, doctors should not interfere. Some activists are lobbying their state governments to pass legislation to ban surgeries that are medically unnecessary such legislation has already been proposed in California and Connecticut.

In the medical community, though, many say the issue should not be legislated, and that medical decision-making for children should remain parents responsibility after consulting with medical professionals.

A 2000 study in the American Journal of Human Biology found that 1.7 percent of babies are born intersex. There are many variations of intersex that manifest as differences in external genitals, internal reproductive organs and sex chromosomes. Another term used is DSD, which stands for Differences of Sex Development.

In Zieselmans case, she has Complete Androgen Insensitivity Syndrome, or CAIS. She was born with external female anatomy and internal testes. This means her body doesnt respond to testosterone and instead converts it to estrogen. In 1982, when Zieselman was 15, doctors removed her testes and told her and her parents that it was a partial hysterectomy, when, in fact, she never had a uterus or ovaries. All she knew was that she would never menstruate or be able to get pregnant.

My parents were told I was born with partially formed reproductive organs, Zieselman said.

She felt betrayed.

I realized I had been lied to by the medical community, by doctors who had been involved in this surgery and diagnosis. The truth was hidden even from my parents, she said.

Zieselman believes her doctors thought they were doing what was in her best interest at the time. But she disagrees.

The procedure, she said, meant having to take hormone replacements for the rest of her life. She maintains that had doctors not removed her gonads, she wouldnt have to take estrogen supplements. The psychological toll of learning the truth about her surgery was also devastating.

Its that feeling of being told youre not good enough. That there is something wrong with your body, that it is something to be shameful of and something to hide. And the fact that youre lied to. It was so shameful that the doctors didnt even tell your parents the whole story, she said.

Learning she is intersex was a turning point for Zieselman. The married mother of two who lives outside of Boston is now the executive director of InterACT, an advocacy group for intersex youth. Shes also publishing a memoir next spring, titled "XOXY."

Activists and medical professionals alike acknowledge that in rare, severe cases involving the reproductive organs like when there is no passage for urine, or when the bladder is on the outside of the body surgery is imperative.

Activists say that the types of surgeries that they condemn are not medical emergencies. Its common for infants with atypical genitalia to undergo procedures within the first year of their lives to make their anatomy look more traditionally male or female. Some baby girls undergo clitoral reduction, a cosmetic surgery, solely for appearance reasons. In 2013, the U.N. Human Rights Council deemed these procedures cruel.

But Jack Elder, chief of pediatric urology at Massachusetts General Hospital, said the term "medically necessary" can be interpreted differently, and he thinks legislation gets in between the physician and patient.

How can somebody else, an outside group, a legislative body, decide what is medically necessary or unnecessary when we're dealing with genital ambiguity? Elder said.

Elder says he and his colleagues dont dictate what parents should do. Instead, he encourages parents of his patients to educate themselves on the pros and cons of having their infant undergo surgery.

We're just trying to help parents and provide some guidance. They might say, What do you think I should do?" he said. "You've got to make a decision at some point, because when they hit puberty, its going to create issues, and the surgery is a lot more involved.

As the debate around these surgeries grows fiercer, pediatric urologists have found themselves being increasingly questioned about their practices surrounding surgeries on intersex babies. WGBH News reached out to three other hospitals in and around Boston and pediatric urologists declined, two of which cited the sensitive nature of the topic.

In March 2018, the Societies for Pediatric Urology and the American Urological Association issued a joint statement on pediatric decision-making. They said they believe medical decision-making for children should remain parents' responsibility after consulting with medical professionals and should not be legislated. The statement also said that children should be involved in these decisions.

In Nov. 2018, the Massachusetts Medical Societys Committee on LGBTQ Matters submitted a report to MMS, recommending hospitals create teams designed to assess the needs of intersex babies and proposing that MMS advocate for a delay of surgery.

Parents who have just welcomed a newborn can find themselves overwhelmed with a multidisciplinary team made up of pediatric urologists, endocrinologists and pediatric gynecologists and social workers.

A Boston-area mother, who asked not to be named to protect the identity of her child, has a daughter with an intersex condition who was treated at a different Boston hospital three years ago. Within a couple days of their daughters birth, she and her husband met with a team of 15 people.

[It] is very overwhelming, and everyone is telling you different things: She doesnt have a uterus, there are testes," she remembered. "They started talking about her vagina hole size and talking about intercourse for her one day. It was hard to talk about my daughters sexual health when she was just born.

She and her husband felt some pressure to have their daughters gonads removed. They connected with an intersex support group in search of advice.

We heard adults telling us that they felt violated, that they had to have multiple surgeries. We were shocked at the horror stories we heard, she said.

When she called their daughters pediatric urologist with their decision not to have their daughters testes removed, she said he was visibly unhappy with their decision. He abruptly ended the meeting.

In the beginning when we made the decision, we were still skeptical. Like, is this real? We were nervous that we only talked with people who were unhappy and rightfully so. But the more we talk about it, the more we feel really strongly against surgeries, she said.

Their daughter could develop secondary male characteristics once she hits puberty, but this is a possibility her parents have accepted. They believe their daughter should decide what she wants to do with her body when shes older.

Dina Matos, executive director of the CARES Foundation, an organization based in New Jersey that offers support for people with Congenital Adrenal Hyperplasia the most common DSD said the organization is not for or against genital reconstructive surgery and that their role is to educate parents and patients.

We always encourage people to get more than one opinion. The one thing we highlight most importantly, is if they decide that surgery is indicated with their child, that they seek out an expert," Matos said. "It really takes the surgeon with significant experience, and we really only refer to three or four surgeons in the country right now.

For some, surgery is never an option. Tatenda Ngwaru, an intersex activist from Zimbabwe, recently moved to the suburbs of Boston.

Some people tried to burn down my father's house and kill all of us. And this was done just because of me, because I have a big mouth, Ngwaru said.

When Ngwaru was born, doctors mistook her enlarged clitoris for a penis. She was raised as a boy for the first 10 years of her life, until doctors discovered she had ovaries. It was what she calls an aha moment she never felt like a boy. But in her small town, going from son to daughter was out of the question.

It had always been treated as an abomination, as bad. Back then they used to say we're the ones who will give bad luck to the community, Ngwaru said.

Her parents, stunned by this news, didnt want her to be bullied, so they urged her to continue wearing a boys uniform throughout high school. It was agonizing.

I remember sleeping at night sometimes and thinking, Couldn't morning just come so that we can get it over with? Or maybe morning shouldn't come at all, because I didn't want to deal with daylight and having to be out and pretending and hiding something. There's nothing as painful as an untold story that you have to hide inside, she said.

Ngwaru waited until she was at college in a different part of Zimbabwe to live as a woman and started Zimbabwes first intersex advocacy organization. But trouble soon followed. She was attacked, her office was raided and her family was threatened.

So she fled for the U.S., seeking asylum from gender persecution. And she thought things would be different here.

I thought, they are promoting transgender lives on their TV shows. Clearly, they must know about intersex. I had a rude awakening. Nobody seemed to know what intersex is. And in America what was most shocking for me are the surgeries that had been done on infants, she said.

Zieselman said she wants attitudes to shift in the way they recently have for transgender people.

With transgender children, what the standard of practice has become is to do reversible procedures first and provide a lot of psycho-social support to the child and family, so no irreversible decisions are made too quickly until the child is really sure about what they want," she said. "Why arent we using the same standard of practice for intersex children?

Massachusetts voters may someday see a push for legislation banning medically unnecessary surgeries on infants. Zieselman said she is in discussion with state lawmakers about proposing a bill "to protect intersex children."

All humans have bodily differences, and if theres nothing making them sick or interfering with their health, then theres no reason to modify them," she said. "Intersex people can grow up without surgery and be happy and healthy.

The link between anabolic steroids and gynecomastia in men – MENAFN.COM

(MENAFN - Arab Times) Gynecomastia is a problem that occurs in some men in whichbreast tissue develops. It is often caused by some type of disruption to theendocrine system. This is the system of the body which consists of glands thatsecrete various hormones, so any thing that upsets the homeostatic balance ofparticular sex hormones can result in gynecomastia.

There are some cases where a man may not have extra breasttissue because of hormonal problems but rather from having too much fat thataccumulates behind the areolae of the chest. This condition is sometimesdistinguished from gynecomastia and is called lipomastia or adipomastia.

Interestingly gynecomastia is not uncommon in newborn maleinfants and is found in from 60 to 90% of newborn baby boys, but thecondition usually goes away on its own. It can occur in about 1/3 of menbetween 25 and 45 and it becomes more prevalent with age.

How steroids causehormonal problems

One of the major factors associated with the development ofgynecomastia in men is the use of anabolic steroids, causing as many as 25% of allcases in men. Steroid abuse has long been a problem in the sports world,and the concern is that there are unpleasant side effects with these drugs.

The steroids often alter the balance of estrogen andandrogen hormones in people. A man usually has a lot of the androgen hormoneslike testosterone and very little estrogen, but the steroids affect theconcentrations. This hormonal imbalance is believed to be the main causativefactor of gynecomastia in men.

Not all of the steroid drugs necessarily cause breastdevelopment, but those that do often do so because they can cause a change inhormone levels. The synthetic steroid mimics the effect of naturally producedtestosterone. Testosterone is the hormone most associated with muscledevelopment in boys at puberty, and it can lead to increased muscle mass asboys mature during adolescence. Unfortunately the body tends to convert theartificial testosterone found in anabolic steroids into estrogen after a whilewhich then leads to breast tissue development.

What can be doneabout gynecomastia ?

The most permanent solution to the problem of gynecomastiais to have breast reduction surgery as is done at such places as theVera Clinicin Turkey. A surgeon canremove the excess breast tissue from the chest area to create a more masculineappearance. A man does have to be healthy enough to undergo surgery though, sothis is something to keep in mind and why consulting with a physician is a goodfirst step in looking for treatment options.

For some men, the breast cancer drug Tamoxifen has provedhelpful in treating their gynecomastia condition. If a man has breast tissuebecause of being overweight, the first step should be to try to lose weight bystarting an exercise program and following a healthy diet. In the end this canonly benefit you even if you later decide on breast reduction surgery.

Don’t wait: Schedule your breast cancer screening at Henry Ford Cancer Institute – Dearborn Press and Guide

Early detection is the best defense to managing breast health.

October is Breast Cancer Awareness Month and a good reminder to schedule your mammogram, perform a self-check in the shower or ask your doctor about your risk factors.

Its important for every woman to know what shes up against regarding breast cancer, says Jessica Bensenhaver, M.D., director of the breast cancer program at Henry Ford Cancer Institute, but the most important things you can do are to be a self-advocate and attend your annual screening.

Breast cancer is one of the most frequently diagnosed cancers in women in the United States. Overall, one in eight women will be diagnosed with breast cancer in her lifetime. However, risk increases with age. According to Dr. Bensenhaver, at age 30, 1 in 217 women are likely to get breast cancer. At age 40, the figure is 1 in 67.

Since breast cancer is treatable at any age when discovered early, routine screenings should be an important part of every womans health plan.

Although most women with breast cancer have no family history of the disease, those with an immediate family member on either parents side should notify their doctor.

Age and family history are among the risk factors women cant control. Others include:

BRCA1 and BRCA2 gene mutations that mean an eight out of 10 chance of getting breast cancer at some point in your life

Race/ethnicity. According to Dr. Bensenhaver, Caucasian women are traditionally more likely to get breast cancer than African Americans. However, if youre younger than 45, African American women are at a higher risk

Breast density. In addition to increasing your risk of breast cancer, having dense breast tissue can make diagnosis of a lump or tumor through standard mammography more challenging. In Michigan, women must legally be notified if their breasts are dense. Sometimes it is recommended that women with dense breasts undergo additional screening methods, like ultrasound or screening tomosynthesis, also known as 3D mammograms

In addition to scheduling regular screenings, women should be familiar with their breasts and see a doctor immediately if they feel a lump, experience persistent pain or observe changes in skin color or texture.

Since worrying about breast cancer can weigh heavily on the mind, the Henry Ford Cancer Institute encourages women to be proactive about their breast health. Dr. Bensenhaver said to lower your overall risk of breast cancer:

Numerous studies have shown that obesity can increase your risk for many types of cancer, including breast cancer. According to the National Cancer Institute, postmenopausal women who are obese have a 20 to 40% increased risk of developing breast cancer.

Consuming one alcoholic drink per day increases your chances of getting breast cancer by at least 5 percent, according to the American Cancer Institute for Cancer Research. Two to three drinks per day raises your risk by 20%.

Although no one knows why, studies show that women who breastfeed have a lower risk of breast cancer. Even just a couple of months of breastfeeding can lower your risk.

In 2002, researchers discovered a connection between Hormone Replacement Therapy (HRT) and increased breast cancer risk. Although HRT can ease postmenopausal symptoms, talk to your doctor about the possible risks and avoid it if possible.

To take the private, at-home assessment, simply visit HenryFord.com/BreastCancerRisk to answer questions about your current health status and fitness levels as well as your family history. The assessment will generate a personalized report that you can download and share with your doctor.

Talking to your doctor is a critical part of the process. Your physician can answer your questions and help you navigate through massive amounts of information available about breast cancer health online. As you try to determine how to reduce your controllable risks, your doctor can cut through all the what ifs to provide compassionate care and straightforward information.

Despite their best efforts, the fact is that some women will face a breast cancer diagnosis. The Henry Ford Cancer Institute has one of the nations leading breast cancer programs, featuring specially trained breast radiologists who read all mammograms and imaging results.

Henry Ford also has the most advanced technologies available to detect and diagnose breast cancer and offers mammography locations throughout southeast and south central Michigan, with day, evening and weekend hours available. Visit HenryFord.com/Mammography for locations and to schedule your mammogram.

When N.C. healthcare wouldn’t cover his top surgery, Owen Conley turned to GoFundMe – The Daily Tar Heel

Conley recently created a GoFundMe page to help cover his future medical bills. Despite this, he said he feels uncomfortable putting his personal life on public display, especially since he hasn't yet come out to his grandmother.

But accessing affordable, supportive health care, he said, has been a challenge. He has rescheduled the surgery twice due to insurance confusion and financial stress.

Because of N.C. State Health Plan's policy, the $9,000 estimated cost of the surgery, and potentially all future trans-related health care, will fall on Conley. He said he has saved his own money, but it will not be enough without crowdsourcing.

He also said it has been difficult to find trans-positive health care providers and surgeons.

This is just one example of how transgender people are left out of the discourse, Ezra Wright, a member of UNCs Sexuality and Gender Alliance said.

There is minimal representation and few doctors that perform gender affirmation surgery, they said.

Anne Stephens, a clinical medicine physician at Campus Health, said she understands that LGBTQ+ healthcare should not have a singular approach.

There is a range of ways individuals may choose to transition and express their gender, she said. Changes may be social factors like name and clothing style, or more medical-based changes with male or female hormone medication. The medical side of student transitions is what she and her colleagues aim to help with.

Conley said that pursuing gender confirmation surgery is the right choice for him. However, medical transitions mark a small piece of the deeper LGBTQ+ identity.

The idea that as a transgender person you need to be transitioning is not true, Wright said. It has nothing to do with validity.

They said that the story of gender does not end with surgery that surgery is not the core of the transgender experience.

Its like gender, Wright said. Transitioning is treated as binary its not.

The transgender and LGBTQ+ experience, Conley said, is somewhat shaped by cultural exceptions and the media. He said that it is extremely important that support for the transgender community be genuine.

There are a lot of people at this University that I have found to be my best supporters, he said. But Im not sure that this University as a whole is cognizant of the struggles that trans people face."

Conley said that there is a prevalence of token queer people or token people of color in the media and University public relations.

In terms of University treatment of trans individuals, he said, a motto that they should go by is 'representation, not exploitation.'

He said acknowledging the successes, not just the dangers and violence, in the LGBTQ+ community is a necessary shift in mindset. He said the resilience of the transgender community is shown through the presence of transgender people in academia, healthcare, the arts and other industries.

Why should someone have to die in order for people to care? he said. The ultimate act of resistance is still being alive.

Conley said he is still discovering his own identity and his advocacy work.

I don't want my narrative to be pigeonholed into being a single-story narrative," he said. There is not a before or an after to my transition, as I am learning.

Conley is often afraid that his identity defines him and his body.

Sometimes when I look in the mirror, I still see a stranger," he said. "I will always be living in a state of transition."

Conleys view of top surgery is not cosmetic.

It's one step closer to becoming someone I recognize to be myself, he said. And quite honestly, it will be a life-saving procedure like any other surgery someone may have.

That last toke for the road could be a downer with pot breathalyzers coming – AOL

LOS ANGELES, Oct 23 (Reuters) - One toke for the road could end up being a total bummer for drivers who smoke pot, with several companies in the United States preparing to market cannabis breathalyzers as legalized marijuana spreads across the country.

Law enforcement agencies will require breathalyzers to detect marijuana as they are "faced with the necessity of stopping more and more motor vehicles being operated under the influence of THC," said Brett Meade, a retired police chief and a senior program manager for Washington-based non-profit group the Police Foundation.

Nearly a dozen U.S. states allow recreational marijuana consumption and 33 states permit pot for medical use. But all states prohibit driving under the influence of marijuana.

Oakland, California-based Hound Labs is one of the companies developing a breathalyzer to detect THC - the component in marijuana that gets people high - and plans to market it in 2020.

Construction companies could be a big part of its market, said Hound Labs Chief Executive Officer Mike Lynn.

"Nobody wants a crane operator 50 stories up to be smoking a joint," he told Reuters.

Lynn, a physician, said pregnancy tests, which can detect minute quantities of hormone, inspired him to tackle the challenge of measuring THC on users' breath.

Separately, Cannabix Technologies Inc based in the Vancouver suburb of Burnaby is testing a pair of devices at different price points.

Its THC Breath Analyzer could be cheap enough at a few hundred dollars per unit to potentially allow parents interested in testing their teenager before turning over the keys to the family car, said Cannabix CEO Rav Mlait.

The U.S. court system would need to consider how to treat evidence from THC breathalyzers.

Assuming a motorist who tested positive with a THC breathalyzer was impaired behind the wheel could be "problematic," said Stanford University law professor Robert MacCoun.

Unlike with alcohol, scientific research has not yet established firm correlations between the amount of marijuana people consume and how impaired they become, MacCoun said in an email.

Paul Armentano, deputy director of the National Organization for the Reform of Marijuana Laws, expressed similar concerns.

But he welcomed breathalyzers as an improvement over existing tests used by police and employers, such as urine analysis that is unable to determine whether marijuana was used recently with the potential for impairment, or days or weeks in the past. Breathalyzers are likely to only detect a user who consumed cannabis within the last few hours.

"A test like that would frankly make sense," Armentano said. "Just like we wouldn't allow employees to have a couple drinks and show up to work." (Additional reporting by Jane Ross in Newark, California; editing by Bill Tarrant and Bill Berkrot)

Right-wing media built the Texas government investigation into custody battle over trans child – Media Matters for America

Texas government officials are parroting right-wing media misinformation about trans youth, including during an appearance on Fox News, as the state is attempting to launch a child abuse investigation into a custody battle over a transgender child whose parents disagree about affirming her gender identity. Anti-trans figures have consistently portrayed the affirmation of trans youth as child abuse.

Right-wing media outlets have dubiously framed the custody battle as a debate over medical intervention -- despite the fact that the child would not be undergoing any such procedures in the near future. They have also pushed misinformation about medical interventions that are widely supported by medical professionals, inaccurately calling them chemical castration -- a false claim which has also been repeated by the Texas attorney general office.

The custody battle is between Anne Georgulas and Jeffrey Younger, two divorced Texas parents of a trans child who goes by Luna and uses female pronouns. Three mental health professionals have diagnosed Luna with gender dysphoria, and Georgulas has accepted her as trans. However, Younger has rejected Lunas gender identity, insisting she is not trans and referring to her by her former name (commonly referred to as a deadname). According to court documents, Younger has engaged in increasingly aggressive behavior, including physical force, toward Georgulas and emotionally abusive behavior toward the child. He has also launched an online campaign, fundraiser, and petition all using the name Luna formerly used.

On October 24, a judge ruled that the parents would share joint custody of Luna despite a jury ruling that Georgulas should have sole custody earlier this week. The judges decision came after major outcry from right-wing media figures and Texas elected officials, including Rep. Dan Crenshaw (R-TX) and Sen. Ted Cruz (R-TX).

Right-wing media led an extensive misinformation campaign about the custody battle, which Texas government officials relied on to justify launching an investigation.

Abbott announced on October 23 that the Texas Office of the Attorney General and Department of Family and Protective Services are looking into the custody case. Government officials in the state usedthat misinformation to justifythe potential investigation. Following the announcement, Texas Assistant Attorney General Jeffrey Mateer sent a letter and issued a press release requesting that the state Department of Family and Protective Services conduct a thorough investigation into possible child abuse to protect the boy in question [from] permanent and potentially irreversible harm by his mother.

Mateer is an allied attorney with the extreme anti-LGBTQ group Alliance Defending Freedom; at least four other ADF allied attorneys worked in the Texas attorney generals office in 2018. In 2017, Mateers federal judicial nomination was withdrawn after some of his extreme anti-LGBTQ comments were uncovered. Notably, Mateer claimed that the existence of trans youth proves that Satans plan is working, and he advocated for the harmful and debunked practice of conversion therapy.

On October 24, Texas Lt. Gov. Dan Patrick went on Fox News The Ingraham Angle, a friendly show for anti-LGBTQ viewpoints, and claimed that at seven, you can't make that decision that will change their life forever -- that you cannot come back, particularly if you go through the full treatment into their teen years. During the segment, Ingraham also called gender-affirming carechild abuse. In another segment from Foxs The Daily Briefing with Dana Perino on October 25, Patrick suggested the legislature would explore the issue in its next session.

The language in Mateers comments and Patricks interviews comes directly from right-wing media, which have taken the custody battle and falsely reframed it to be about supposedly irreversible medical procedures. In fact, therapists have not recommended any medical interventions for Luna, but rather would allow her to dress and otherwise identify as a girl. The Washington Post has noted:

Could CRISPR Technology Rise As A Hero In The Era Of Antibiotic Resistance? – Kaiser Health News

CRISPR has been making waves with its success in fighting rare genetic diseases, but could it also help turn bacteriums machinery against itself? In the era of superbugs, scientists are hopeful the technology can be a game-changer. Meanwhile, GSK has announced a late-stage study for its new antibiotic to fight urinary tract infections and gonorrhea.

The New York Times:Is Crispr The Next Antibiotic?For decades, scientists and doctors have treated common bacterial and viral infections with fairly blunt therapies. If you developed a sinus infection or a stomach bug, you would likely be given a broad-spectrum antibiotic that would clear out many different types of bacteria. Antiviral drugs help treat viral illnesses in much the same way, by hindering the pathogens ability to reproduce and spread in the body. (Sheikh, 10/28)

Reuters:GlaxoSmithKline Starts Late-Stage Trial For Experimental AntibioticGlaxoSmithKline Plc said on Monday it has begun a late-stage study testing its experimental antibiotic in patients with urinary tract infection and gonorrhoea, a type of sexually transmitted infection. The antibiotic, gepotidacin, is the first of a new class of drugs and is expected to treat the two common infections caused by bacteria - identified as antibiotic resistant threats by U.S. health regulators.

Young scientists urge New Zealand’s Green Party to embrace CRISPR for ‘sake of the climate’ – Genetic Literacy Project

Recently, there has been a shift in societys view of genetic modification and its potential applications in the fight against climate change. This has led to a call for changes in our current policies from farmers and MPs alike. However, due to the Green Partys current stance on this topic, New Zealand is unable to utilise genetic modification for anything that is not laboratory-based.

I am a member of the Emerging Scientists for Climate Action society, which involves students from universities all over New Zealand. We are writing an open letter to the Greens to encourage them to review their stance on genetic modification and the current laws and regulations around genetic engineering. Our overarching goal to tackle climate change aligns with the Greens, and they are in a position to make positive change. We have 155 signatures from emerging scientists (aged under 30) in support.

[Editors note: Deborah Paull is studying for a Masters of Science in Microbiology at the University of Canterbury.]

Genetic modification is a controversial topic, and there is much misunderstanding about its techniques and applications. Genetic modification (aka genetic engineering) uses gene editing technologies and knowledge of genetics to make changes in an organism for a specific outcome. For example, a plant could be genetically modified to grow bigger to produce a higher yield.

CRISPR Therapeutics AG (CRSP) Q3 Earnings and Revenues Surpass Estimates – Yahoo Finance

CRISPR Therapeutics AG (CRSP) came out with quarterly earnings of $2.40 per share, beating the Zacks Consensus Estimate of a loss of $0.95 per share. This compares to loss of $1.07 per share a year ago. These figures are adjusted for non-recurring items.

This quarterly report represents an earnings surprise of 352.63%. A quarter ago, it was expected that this company would post a loss of $0.81 per share when it actually produced a loss of $1.01, delivering a surprise of -24.69%.

Over the last four quarters, the company has surpassed consensus EPS estimates just once.

CRISPR Therapeutics AG, which belongs to the Zacks Medical - Biomedical and Genetics industry, posted revenues of $211.93 million for the quarter ended September 2019, surpassing the Zacks Consensus Estimate by 3,252.23%. This compares to year-ago revenues of $0.56 million. The company has topped consensus revenue estimates just once over the last four quarters.

The sustainability of the stock's immediate price movement based on the recently-released numbers and future earnings expectations will mostly depend on management's commentary on the earnings call.

CRISPR Therapeutics AG shares have added about 39.5% since the beginning of the year versus the S&P 500's gain of 20.6%.

What's Next for CRISPR Therapeutics AG?

While CRISPR Therapeutics AG has outperformed the market so far this year, the question that comes to investors' minds is: what's next for the stock?

There are no easy answers to this key question, but one reliable measure that can help investors address this is the company's earnings outlook. Not only does this include current consensus earnings expectations for the coming quarter(s), but also how these expectations have changed lately.

Empirical research shows a strong correlation between near-term stock movements and trends in earnings estimate revisions.

Intellia Therapeutics Presents In Vivo and Ex Vivo Data at the 2019 Annual Congress of the European Society of Gene and Cell Therapy (ESGCT) – Yahoo…

First reported consecutive in vivo gene knockout and insertion achieves therapeutically relevant results in an alpha-1 antitrypsin deficiency mouse model

Inserted highly active WT1-TCR into the endogenous TCR locus for potential improved treatments for hematological and solid malignancies

CAMBRIDGE, Mass., Oct. 24, 2019 (GLOBE NEWSWIRE) -- Intellia Therapeutics, Inc. (NTLA), a leading genome editing company focused on the development of curative therapeutics using CRISPR/Cas9 technology is presenting one oral presentation and four poster presentations at the 27th Annual Congress of the European Society of Gene and Cell Therapy (ESGCT) meeting taking place October 22-25, 2019, in Barcelona, Spain.

We are excited to share progress across Intellias in vivo and ex vivo programs at this important scientific venue, said Laura Sepp-Lorenzino, Ph.D., chief scientific officer, Intellia Therapeutics. Our data shows the complexity of the edits we are able to make with CRISPR/Cas9, while achieving important therapeutically relevant results. We are building on the success of our modular platform now having demonstrated consecutive targeted knockout and insertion genome edits in preclinical studies. Additionally, we presented data from our engineered cell therapy program, which continues to demonstrate the use of CRISPR/Cas9 for combined knockout and targeted integration in human T cells.

Intellia Demonstrates Consecutive In Vivo Genome Editing in Alpha-1 Antitrypsin Deficiency Mouse Model

Intellias oral presentation highlights its alpha-1 antitrypsin deficiency (AATD) study showing that consecutive dosing of two distinct lipid nanoparticle (LNP) formulations, in adultmice, achieves two targeted genome editing events, resulting in knocking out the faulty gene and restoring therapeutic levels of normal alpha-1 antitrypsin protein (hAAT). Intellias approach for AATD uses a modular hybrid delivery system combining a non-viral LNP which encapsulates CRISPR/Cas9 with an adeno-associated virus (AAV) carrying donor DNA template. Compared to traditional viral-based delivery of gene editing components, Intellias LNP delivery system can overcome the inherent limitations of immunogenicity to facilitate multiple in vivo gene editing events.

In a mouse model harboring the human PiZ allele, the most severe genetic defect in AATD patients, Intellia first reduced expression of the defective protein using gene knockout. Three weeks following the PiZ allele knockout, Intellia inserted the normal human alpha-1 antitrypsin gene, resulting in stable (throughout 12 weeks of observation), therapeutically relevant circulating protein levels. In the study, a sustained reduction of the circulating PiZ protein levels of >98% was observed for over 15 weeks. This is the first in vivo demonstration of a non-viral delivery platform, enabling a consecutive dosing approach for achieving multiple genome edits in the same tissue of the same animal. Intellias oral presentation, titled In Vivo Gene Knockout Followed by Targeted Gene Insertion Results in Simultaneous Reduced Mutant Protein Levels and Durable Transgene Expression, will be given by Anthony Forget, Ph.D., on October 25, 2019. This presentationwill be available on Intellias website at http://www.intelliatx.com.

Intellias Poster Presentations

WT1-Specific TCR Engineered Cell Therapy Studies

Intellia presented new in vitro data showing that CRISPR/Cas9-mediated genome editing for in locus insertion, combined with endogenous T Cell Receptor (TCR) knockout, leads to significant reduction in mispairing of endogenous and transferred TCR chains. This approach is expected to generate transgenic-TCR (tg-TCR) T cell therapies for hematological cancers and solid tumors. Results demonstrate a highly efficient reduction of >98% in endogenous TCR and chains while reaching >70% insertion rates of tg-TCRs without further purification. The poster titled Engineering of Highly Functional and Specific Transgenic T Cell Receptor (TCR) T Cells Using CRISPR-Mediated In Locus Insertion Combined with Endogenous TCR Knockout, was presented on October 24, 2019, by Birgit Schultes, Ph.D.

Researchers also presented in vitro data showing that a library of WT1-specific TCRs were generated, several of which Intellia is currently evaluating as part of its lead engineered cell therapy program targeting Acute Myeloid Leukemia (AML). This presentation, Generation of a Library of WT1-Specific T Cell Receptors (TCR) for TCR Gene Edited T Cell Therapy of Acute Leukemia, was presented on October 23, 2019 by Intellias collaborator, Erica Carnevale, Ph.D., IRCCS Ospedale San Raffaele.

Primary Hyperoxaluria Study

Intellia showed the continued progression of its modular platform capability using CRISPR/Cas9 to knockout either hydroxyacid oxidase 1 (Hao1) or lactate dehydrogenase A (Ldha), leading to a dose-dependent and persistent reduction of urinary oxalate levels in a Primary Hyperoxaluria Type 1 (PH1) mouse model. Data shows Ldha gene disruption also decreased LDH enzyme activity in the liver and did not impair the disposition of lactate in either wild type or renally-impaired mice. These results highlight the potential of editing genes in the glyoxylate detoxification pathway using a non-viral delivery approach as a one-time treatment option for PH1. These data were presented as a poster, titled CRISPR/Cas9-Mediated Gene Knockout to Address Primary Hyperoxaluria, by Sean Burns, M.D., on October 24, 2019.

Off-Target Screening Platform

Intellia demonstrated its approach to assess off-target activity to identify highly specific CRISPR/Cas9 guides. Results from targeted off-target sequencing in edited cells showed that biochemical off-target discovery approaches were the most sensitive and accurate. These data were presented as a poster on October 23, 2019, titled In Silico, Biochemical and Cell-Based Integrative Genomics Identifies Precise CRISPR/Cas9 Targets for Human Therapeutics, by Dan OConnell, Ph.D.

Extending the life of hi-vis garments – Laundry and Cleaning News

SUBMITTED EDITORIAL BY HYDROFINITY

Did you know that most hi-vis garments only have a maximum life of 25 washes, with many losing their reflective properties after just five washes? That means if hi-vis clothes are washed twice a week; they will no longer comply with current EN ISO 20471:2013 standards in just 12 weeks.

To ensure workwear and PPE help people stay safe and seen in challenging and dangerous working conditions, items need to be replaced when faded, torn, dirty, soiled, worn, defaced, or not visible from 300m, day or night. When hi-vis tape is damaged or soiled, it fades to a matt, dull colour. If its not reflective or shiny, its time to replace the garment.

Why do reflective strips fade after washing?

It is essential to maintain the cleanliness of high visibility garments. If they are dirty the visibility will be compromised.

Reflection strips are very sensitive to heat and chemistry, but most washing machines need high temperatures and large doses of detergent and other chemistry to remove industrial soiling such as oil and contaminants.

How to maintain long term visibility?

There is a solution for extending the life of hi-vis garments though. The Hydrofinity commercial washing machine - which uses XOrb technology can help reflective strips keep their reflectivity for up to 50 washes, doubling the maximum life of most hi-vis garments!

Rigorous life extension testing that was verified via a third party earlier this year, show hi-vis strips that were washed in the Hydrofinity machine had a significantly higher retroreflectivity score after 50 washes than hi-vis strips washed in a comparison washing machine.

The control sample (which was unwashed) had a retroreflectivity score (CIL/m2) of 346. The sample washed in the Hydrofinity machine had a score of 314 and the sample washed in the conventional machine had a score of 98 after 50 washes.

Mike Ferrand, managing director at Hydrofinity explains why the Hydrofinity machine can extend the life of reflective strips.

The XOrbs used in the Hydrofinity machine provide a gentle agitation which significantly reduces the damage caused to the high-tech fabrics and reflective trim whereas conventional machines tend to rely on aggressive agitation to clean reflective gear.

"Our machine also uses less chemistry and washes at lower temperatures than most conventional machines which helps hi-vis strips keep their reflective properties for longer. We aim to support textile service companies in reducing their spend on new textiles whilst reducing waste.

Case study: Georges, France

Hydrofinity customer, Georges, have 10 Hydrofinity machines across their five sites in France and specialise in the cleaning and maintenance of workwear. They currently process the outfits of 25,000 employees and have plenty of high-profile customers including SNCF, Renault Design and Air France.

Georges recently won the contract to clean the PPE of workers restoring the Notre-Dame Cathedral, this was because they can remove all traces of ash and lead particles whilst prolonging the life of the uniform. To read more about Georges, http://mygeorges.fr/
